Eingestrahlte

Eingestrahlte is a German adjectival past participle used to describe objects that have been exposed to radiation. The term appears mainly in technical and scientific contexts and is less common in everyday language. It derives from the verb to irradiate or to beam, and it signals the state of a material or sample after exposure to a radiation source.

In practice, the phrase eingestrahlte Proben or eingestrahlte Materialien refers to samples that have undergone irradiation in a controlled setting. Such irradiation can serve purposes like studying radiation effects, altering material properties, sterilization, or inducing luminescent effects. The description focuses on the resulting state rather than on the irradiation process itself, so the specific dose, radiation type (ionizing versus non-ionizing), and exposure time must be stated separately to convey the experiment’s conditions.

Compared with related terms, eingestrahlte is less common than bestrahlt (irradiated) or ausgesetzt der Strahlung (exposed to radiation). In contexts that distinguish the incoming radiation from the irradiation process, German uses Einstrahlung for the incident radiation and Bestrahlung for irradiation by a source. Eingestrahlte emphasizes the post-exposure condition of the object rather than the act of irradiation, which is useful when describing results, properties, or subsequent handling of the material.

Grammatical notes: as an adjective, eingestrahlte agrees with the noun in gender and number, e.g., eingestrahlte Proben (feminine plural) or eingestrahltes Material (neuter singular).
